President Donald Trump stepped up attacks on his handpicked Federal Reserve chairman on Wednesday, claiming Jerome Powell has “low IQ” and suggesting the list of potential replacements has been narrowed to three or four people.

Buzz is building that President Trump could announce Fed Chair Powell's replacement sooner rather than later, even though his term doesn't end until next year.

President Donald Trump has never had a shortage of targets for his ire. From the establishment media, to #NeverTrump Democrats, to even within his own MAGA inner circle, Trump has little issue calling out those who may impede or impugn his work for the American people.
